Patented July 27, 1943 y This `invention `relates' toflre apparatus ofthe portable type and, more particularly to vthe motor type', of enginein which the pumping apparatus svactivated from theengine ofthe truck.

In the majority of instances, the `(attent of the fire is such that theimmediately available supply of water will be sufficient to extingush itpromptly andwith little damage to the premises. With the' ordinaryapparatus-it is "necessary to employ for such hres either'jagchernicalapparatus or to end a plurality,ofciiecigivalvd inrets r5.1 Leading fromeaeumanifoiatc the banal t is a valved inlety pipe I6, and, associatedWith the tank are low and'l'iighpressure pumps'l'l and I`8 respecrs incorrrmumqauon withfmelmterier'ef tank connect ythe vrire 4apparatus withVa hydrant o1- u other sourceof water, before'an'y supplycan oe had atthe fir e, `ths,l 4in manycases', resulting delay 4and consquent;g'rov'vth of a I niuor emilia-f gration to one ormajor proportions;

important object ,of the present is to'provide af re apparatusincluding' afstruc#` y ture such that a supply of Water is immeriiatelyy available, and Without attachment ci thev appa-- ratus to ahydrantor other source, andvvhich` apparatus maybejrriadj the source forali nec-A essary hose lines "in any but 'thejmost cxtreme cases.

A second object is the provision .ofanapparatusof` this type'havingmeans vfhereby the' pressurev at the linesmaybereadily 'and closelycontrolled and jin which a pluralityl4 'of diier'ent pressures may `loesimultaneously j`prvided.' the invention is the produ tion of lapparatus`QI ,thisfcliafaoter 'which is;

Another objectjof simple in its construction and operation, and may b'ereadily incorporated in f lretrucls of the usual construction;

`These and other4 wherein, `for the Vpurpose of illustration, have showna preferred embodiment of my invention and wherein:

Each 'manifold I2 has at oneend thereopreterably the forward end, a plurality of valved outlets I4and at its opposite @jaar am `by' the sofi-1 Y s'truction'shown in theaccompanying drawing".

' thejhose lirie's4 already laid to the re,` and will ymicted to each"II] 4and its Adischarge 2Q Vin communication *With both of man Holdsy I2through a conduit 'ZI having `che' c'k--valv'ed` communication with themanif oidsatfzz.A l i The highpressurepur'np I8` is provided with aninlet header 23 adapted fo'r -cpnnectionjwith the hydrant 'or other'sourcej'of water and connected with tank I6 through" fafv'lv'ed vbranchline 24.

The discharge 25 of this pump is connected to a manifold 26, the ends ofwhich areprovided with onefor n ioreJ valve outlets 2l to which hoselines'i mayjlbe'attached. AThis manifold 26 is connected with" ma Iiifolds'` i2" through valved branches 29.- Pumps'll and AINBA of course,be driven either directlyfrorn-theinotor of the truck I I, or byseparatemotors, as desired.` 'f` It will be obvious that apparatus vorthis type will be extremely flexible in its operation. Arriv-` ing' atarajpuinp I1 rnay be set in -operation and hose lines attached to outletsI4 utilized to deliver the contents of tanl-I tothe re. If it appearsthat the fire Yis of such serious nature that the contents, of the tankwill 'notjprove sfcient to extinguish the same, the inlet header 23 ofpump" I8 may becorinected to one or more hydrants to supply-`additiohalWater, or such hydrants,` if available, maybe connected tothe inlets [5of manifolds I2". A second engine arriving' on the scene may connect anoutlet I4 of a manifold I2 to the manifold I2' ofthe engine first toarriveon' thescene,` as` by connecting line lhandthis procedure maybevfollowed by all succeeding engines. v Thisv will render the Watercarried or supplied by' those' 'engines available at avoid the'necessityof leading fresh lines thereto. 'I 'hs turn, will prevent entanglementand confusion ofthe-lines, andadura-stain a much moreorderly procedure.Through a series of the connections 3G, Walter may beftransported for aconsiderable distance, 4 from a pondA or creek, as is often necessary inrural districts' Where hydrant connections areoften not availahlafor sopoorly supplied with .vvatefr that;a'jsuflicientarnount cannot bebtair'ied'threfrorn.

with an assisting engine; ler1 engines; conf' riia'nifol" viusthattherel w1.l"always -be4 `available a sufl'lcient amount of Water' to'coinicaletel'y supply hose and the pressures delivered to the manifoldsI2 are 100 pounds on each manifold, the valve line' I 6 of one of themanifolds may be' opened 'so that4 the pressure in the manifold isreducedto 80 pounds. Pump I8 may be operated tovdeliver a; pressure of50 pounds to its manifold 26. It will .j be understood that at this timethe check valves l of branches 22 will be closed due to the fact thatthe `pressure in eitherunanifold-will exceed the mean pressure deliveredby pump I'Iand.

pump I'Iv is at this time discharging through its relief valve 3I intothe tank I0. If the supply to-eithenmanifold I2 suddenlyfails, pump Ilwill immediately becomey effective to deliver water tothat .manifold so`that therewill be no failure of water at the. re, eventhough thepressure may be somewhat lower than that desired.

The pressure gauges employed, together with the .valve systems, venablea single .'operatorrto control all discharge pressure and water fromvthe controlling engine, anyexcess pressure delivered being bled throughline I6 into tankv It!` and, if necessary,`wasting through the overflowIlla. f
